Z-scorea composite score, summarizing the weighted results of a number of ACCOUNTING RATIOS, that claims to predict a company's likelihood of failure. Z-scores were developed by distinguishing the values of various performance-and-liquidity ratios for companies which had gone bankrupt and for those which had prospered. Those accounting ratios which proved t o discriminate effectively between failed companies and successful ones were incorporated in a standard formula to calculate an aggregate Z-score. Analysts can calculate Z-scores for particular companies, and use the results to try to predict whether companies are likely to fail.
